Rydberg excitons in CuO at millikelvin temperatures
Julian Heckötter, David Janas, Marc Aßmann +1
Rydberg excitons in the semiconductor CuO have been observed in absorption experiments up to a principal quantum number of n = 28 at millikelvin temperatures [1]. Here, we exte…
Effective interaction dynamics of Rydberg excitons
Binodbihari Panda, Julian Heckötter, Simon Siegeroth +2
Rydberg states of excitons in CuO are known to interact strongly with other carriers in their surrounding such as other excitons, free charge carriers and static charged impuri…
Quantum coherence of a long-lifetime exciton-polariton condensate
Yannik Brune, Elena Rozas, Ken West +6
In recent years, quantum information science has made significant progress, leading to a multitude of quantum protocols for the most diverse applications. States carrying resources…
Nonlinear Rydberg exciton-polaritons in CuO microcavities
Maxim Makhonin, Anthonin Delphan, Kok Wee Song +13
Rydberg excitons (analogues of Rydberg atoms in condensed matter systems) are highly excited bound electron-hole states with large Bohr radii. The interaction between them as well…
Neutralization of impurities by cw-excitation of high- Rydberg-excitons
Julian Heckötter, Binodbihari Panda, Katharina Brägelmann +1
We investigate the neutralization of charged defects in a CuO crystal experimentally with a cw two-color pump-probe setup. We demonstrate that the excitation of high-lying Rydb…
Taming Charged Defects: Large Scale Purification in Semiconductors using Rydberg Excitons
Martin Bergen, Valentin Walther, Binodbihari Panda +4
We investigate the interaction between highly excited Rydberg excitons and charged impurities in the semiconductor Cuprous Oxide. We find that it is long-ranged and based on charge…
